The Rosato law has established a new electoral system featuring single-member districts (S.M.Ds) along with a prevailing proportional tier. S.M.Ds are typically associated with individual incentives to cultivate a personal vote and with a more direct link between representatives and their local constituency. This article investigates patterns of personalized votes in the Italian elections of March 2018 by analysing voting data about candidates for the Chamber of Deputies who ran in the plurality tier. Results reveal that only a minor – although not negligible – portion of Italian voters cast their ballot for an individual candidate only, and that these votes had almost no impact on the outcomes of competition in S.M.Ds. Moreover, some interesting differences across geographical areas, parties and coalitions emerge in the use of personalized vote.  相似文献

ABSTRACT

Mortar is of all masonry components the most difficult to be experimentally characterized in heritage buildings. This article investigates the possibility of combining different in-situ and laboratory minor destructive testing (MDT) techniques to assess the strength of mortar in historical brickwork. Lime mortar and clay brick walls were built in the laboratory and then tested in order to derive empirical correlation rules among three different MDT techniques: double punch test (DPT), helix pull-out test (HPT), and pin penetration test (PPT). The outcomes of this activity were used eventually to assess the mortar properties of an important historical heritage structure, Casa Puig i Cadafalch, located near Barcelona. The research is intended to promote the use of MDT in studies and conservation works on built cultural heritage by providing criteria for the evaluation of the strength of existing mortar with respectful sampling and testing techniques.  相似文献

In this article, one of the procedures proposed in literature for the design of viscous dampers to be inserted in existing buildings is examined and extended to 3D eccentric buildings. The proposed procedure has been verified through a case study characterized by a six-story RC building. Both plan-symmetric and plan-asymmetric configurations have been considered for comparisons. The effect of considering the plan-asymmetry in the design has been studied. Moreover, also the importance of considering the higher modes has been investigated. The effectiveness of the design procedure has been then evaluated through the comparison with nonlinear dynamic analyses.  相似文献

Management of Italy's heritage has been in increasing turmoil since 1993. This paper identifies and reviews significant reform attempts, including outsourcing, devolution, managerialism and privatisation. The authors propose a framework for improved understanding of the various solutions examined – distinguishing between professional and organisational centralisation. It is argued that while decentralised organisational management can have positive effects, effective protection of heritage in Italy over the centuries has depended on a complex set of rules concerning stewardship and protection, relying upon centralised professional control. This still has positive value and needs to be preserved through the reform process.  相似文献

The skeletal remains of an adult female have been exhumed in an 11th century tomb in the mediaeval Jewish cemetery of Ronda Sur, in the city of Lucena (Córdoba, Spain). Examination of the skull and mandible revealed evidences of bilateral condylar fracture and dislocation. Lesions were observed macroscopically and radiology was used as a complementary method of scrutiny, especially in cases of unclear observation. Irregular morphology of the condyles and coronoid processes, shallow glenoid fossa, altered and abnormal joint surfaces anterior to the glenoid fossa, and reduced height of both ascending rami were observed. Ante‐mortem tooth loss, slight wear of occlusal surface and asymmetrical occlusal deposit of dental calculus were found. Radiologically, degenerative changes in the condyles and reparative bone in both coronoid processes have been identified. Dislocation of the condyles and lack of adequate treatment probably led to disruption of masticatory patterns and related structures, such as muscle attachments, articular disc and ligaments. Bilateral remodelled fracture and the altered appearance of the joint structures could probably mean that the individual survived the injury by several years. This type of fracture could be the consequence of direct blow to the mental or submental region that was transmitted in a direction that raised the mandible, causing the condylar head to collide directly with the mandibular fossa. Very few mandibular fractures in ancient skulls have been described in Spain, and this case is the first example found in a Spanish archaeological skeletal assemblage.

This study illustrates an exploratory approach based on a Multiway Factor Analysis (MFA) to estimate rapidity of change in complex urban systems, based on “fast” and “slow” variables. The proposed methodology was applied to 18 socioeconomic indicators of long‐term (1960–2010) transformations in 115 municipalities of Athens’ metropolitan area (Greece), including demography, land‐use/planning, and urban form and functions. Athens was regarded as a dynamic urban area with diversified structures and functions at the local scale, expanding through a self‐organized pattern rather than a centralized planning strategy. Athens’ urban system was described using nine supplementary (topographic and territorial) variables and 30 independent indicators assessing the local context in recent times. Exploratory data analysis found an increasing connectedness and redundancy among socioeconomic indicators during the phase of largest urban expansion (1960–1990). Only the rate of population growth was classified as a “fast” variable for all five decades investigated. The overall rapidity of change was higher in 1960–1970, 1980–1990, and 2000–2010, decades that coincided with specific phases of urban expansion driven by migration inflow, second‐home suburbanization, and Olympic games, respectively. Rapidity of change was high for functional indicators during all five decades studied, while demography indicators changed more rapidly in the first three decades and land‐use/planning indicators in the last two decades. Rapidity of change was highest in peri‐urban municipalities with a highly diversified economic structure dominated by industry. Our methodology provides a comprehensive overview of the transformations of a complex urban system, quantifying low‐level indicators that are rarely assessed in the mainstream literature on urban studies. These results may contribute to design policies addressing complexity and promoting resilience in expanding metropolitan areas.  相似文献

This article surveys the work of the controversial historian and internationalist Arnold J. Toynbee (1889–1975). In particular, it examines Toynbee’s understanding of foreign politics and his constant search for a stable world order. From the idealism of his youth, through his temporary disenchantment with his youthful expectations, to the religiously inspired utopianism of his final years, this essay discusses the development of Toynbee’s work and understanding of international affairs throughout the twentieth century.  相似文献

ABSTRACT

This article discusses the use of Nazi sources for the study of Fascist policy towards Jews in 1940–1943. By exposing the gap between the Nazi perception of and the reality of the Fascist policy towards Jews in Italian-occupied south-eastern France, the article demonstrates that Rome’s refusal to hand over Jews for deportation did not contradict the fundamental anti-Semitic nature of its Jewish policy in that context. Thus, the article highlights the risks for historians to read Fascist Jewish policy through Nazi lenses and thereby fall prey to stereotypical characterizations of the Italians as insubordinate, scheming and driven by what an S.S. official disparagingly labelled a ‘Jewish-friendly attitude’. At the same time, the article shows that, when combined with Fascist sources, Nazi sources can help shed light on the conceptual divide that underpinned the Axis partners’ disagreement over the means by which the ‘Jewish problem’ should be ‘solved’, thereby exposing the analytical limitations of the current prevailing understanding of the Fascist refusal to hand over the Jews as purely the outcome of ‘pragmatic’ opportunistic considerations.  相似文献

Nodes and places: complexities of railway station redevelopment   总被引:2,自引:0,他引:2  
An interpretation of the redevelopment prospects of railway stations and their surroundings is proposed. Station locations are at the same time nodes and places, affected by both global and local dynamics. Their potential roles within increased transport integration and emerging multi‐centered urban regions provide the foundations for their transformation. However, the task is a complex one, as a discussion of the issues connected with the intensification of flows, the accumulation of activities, and the tangle of actors which characterize these projects shows. More attention must be paid to the integration of the node and place dimensions and of diverging redevelopment strategies.  相似文献

This study outlines the circulation of Phoenician–Punic amphorae in northern coastal Etruria, with a particular focus on Pisa (Italy), where their presence has been attested since the mid-eighth century BCE. A set of specimens from Piazza del Duomo was analysed by minero-petrographic and geochemical techniques. The results were compared with literature data from Mediterranean production areas. The research allowed a better definition of the role of Etruscan Pisa in the frame of commercial and cultural routes in the Mediterranean, specifically in the Tyrrhenian area, also providing the opportunity to review the attestations of Phoenician–Punic amphora on a regional scale.  相似文献
